The DAC1-13 is an extreme duty Type 1+2 pluggable SPD designed to protect AC powerline at the main switchboard of an installation equipped with lightning rod. The technology ‘Multi-varistor” allows a very high discharge current capability in small dimensions and the best possible behavior to the AC network (no follow current). In the light of their high discharge capability, the DAC1-13 surge protectors are especially compact and are available in multipolar versions to protect single or 3-phase AC networks.
